Argh, I've missed the required patterns are incorporated already
in your patch. I'll test it again with sh-softfp-predicate-fix

Just in case it we accepted that SNaNs and QNaNs are not exclusive and

Is this only a proof-of-concept, because you only change the ne[sd]f2

For an actual patch, you need to use the SL* macros from
config/sh/lib1funcs.h because the SH1 does not have delayed branches.
I refer you to the various issues I have raised with attributes proposals
in WG14 in the past, some at least of which have also been forwarded to
WG21. The committees have generally chosen not to listen to compatibility
concerns, except insofar as WG14 ended up not adopting general attribute

Hi,
You mean I should define insn like this:
(define_insn "*iorqi3_imm"
[(set (mem:QI (match_operand:HI 0 "register_operand" "b"))
(ior:QI (mem:QI (match_operand:HI 1 "register_operand" "b")
(mem:QI (plus: HI (match_operand:HI 2
"register_operand" "f")
Quoting "Joseph S. Myers" :
That diff does not appear to relate to undefined behavior. GCC considers
these out-of-range conversions to yield an unspecified value, possibly
raising an exception, as per Annex F, and does not take the liberty of
optimizing on the basis of them being undefined when
Quoting Joe Buck :
RMS is unlikely to abandon the GFDL because the features that many object
to as non-free are intentionally chosen, in part to make sure that he can
get his message out even in situations where a distributor would not agree
with that message. I think he hasn't gotten over ESR'

As a license statement, that's accurate. As a policy statement, the FSF
